Saipan's Grotto is among the world's best single dives for the novice and the expert. You decend 110 steps to large rock to step into the inner Grotto that has three primary exits into the open ocean where a scuba diver can enter caves, travel on a wall, or adventure to the Temple of Doom. Another less prominant opening takes one down a cavern exiting at 110 feet or the novice can stay insice the 40 to 70 original protected Grotto. The water color is legendary as are the creatures. Turtles and white or black tip reef shark and eels fequent the Grotto at night as well. This is a five star dive even compared to Palau's Blue Corner.
